Note. Hydraulic oil is supplied locally and acts on the corresponding underwater valve actuator. “Providing hydraulic oil on site” can be locally stored pressurized fluid or hydraulic
Cable supply. High-speed data automatic measurement recording is possible using the electro-hydraulic control system. Multi-channel technology for electrical signals reduces power in the umbilical
The number of wires.
